The IRS has finalized its Broker Rule, requiring all cryptocurrency exchanges to subject their users to Know-Your-Customer (KYC) measures.
The rule defines control over offered services and deems developers of user interfaces as Virtual Asset Service Providers, subject to anti-money laundering obligations.
The Blockchain Association has filed a lawsuit against the IRS and the Treasury Department, claiming the rule is unconstitutional.
Senator Ted Cruz introduced a joint resolution to disapprove of the IRS rule, which gained overwhelming support in the Senate.
